It was announced under the name Coalition to Walk & Run Again. “As an industry, we would not want to see these people victimized twice,” says Tom Fise, the association’s executive director.

Costs for a below-knee device average $8,000 to $12,000 each and $40,000 to $60,000 for above-knee prosthetics.

The association's offer covers only a portion of expected costs for amputees: victims who lost both legs could face medical bills of $450,000 over the next five years, according to a Department of Defense and the Department of Veterans Affairs study.

The association estimates that at least half the Boston Marathon amputees lack enough insurance to cover their prosthetic costs as some policies provide as little as $1,000 per device or only provide one artificial limb. Many prosthetics need replacing every five to seven years.

"Many of these patients even today don't know what their insurance has in store for them, nor do we,” Fise says, “so the program is about making sure the decisions to restore mobility to these patients are made as independent as we can from any considerations of what the insurance limitations may be."

The Coalition will use its network of companies to provide for the prosthetic and orthotic needs of any Boston Marathon bombing victim (excluding physician and hospital costs).

Additionally, a relief group called One Fund has brought in $27.7 million in donations that they’ve promised to pay out to victims. Country singer Kenny Chesney’s “Spread the Love” fund will use proceeds from sales of that single to help buy prosthetics and provide other care to amputees.
